# Cloud Water vs WhoseUp

The clearest difference is in-app purchases: Cloud Water at none against WhoseUp's 1. Cloud Water also leads on ratings volume (18 vs 3) and iOS requirement (12.0 vs 17.6). WhoseUp's advantage is review sentiment (100% vs 67%) and rating (5.0 vs 4.6). On price, ads and device support there is nothing between them.

Both are free to download. WhoseUp sells 1 one-off in-app purchase. Cloud Water asks for nothing beyond the download.

WhoseUp holds the better App Store score, 5.0 against 4.6.
